ABSTRACT
OBJECTIVE: To observe the therapeutic effect and mechanism of modified Banxia Houpu decoction on globus hystericus. METHODS: The 95 patients with globus hystericus were randomly divided into a treatment group of 46 cases treated with modified Banxia Houpu decoction and a control group of 49 cases treated with Manyanshuning (Granula for Clearing the Throat). In addition, a normal group of 24 healthy people was set up. SCL-90 scale was adopted to observe the therapeutic effect, evaluate the psychological state of patients and build a database on combination of four diagnoses. RESULTS: The effect of the modified Banxia Houpo decoction was better than that of the control group in relieving depression, anxiety and improving the psychological state (P<0.05 or P<0.01). CONCLUSION: Modified Banxia Houpu decoction has definite therapeutic effect on globus hystericus. Its mechanism may be related to its function in relieving depression and anxiety and regulating the psychological state.

BACKGROUND & OBJECTIVE: Various chemically synthetic anti-angiogenesis agents have serious side effects. The traditional Chinese medicine has attracted considerable attention because of its low toxicity. This study was to explore the inhibitory effects of Scutellaria barbatae D. Don, a kind of traditional Chinese medicinal anti-cancer herb, on tumor angiogenesis, and investigate its mechanism. METHODS: Matrigel plug and human umbilical vascular endothelial cells (HUVECs) were used to construct in vivo and in vitro models of angiogenesis to assess the effect of Scutellaria barbatae D. Don on angiogenesis. After cultured with Scutellaria barbatae D. Don, the migration of endothelial cells was examined by Transwell chamber; the expression of vascular endothelial growth factor (VEGF) in HeLa cells was detected by enzyme-linked immunosorbent assay (ELISA). RESULTS: Scutellaria barbatae D. Don significantly inhibited angiogenesis in Matrigel; the tube formation number was significantly lower in 20% and 40% medicated serum groups containing Scutellaria barbatae D. Don than in 20% and 40% drug-free serum groups (5.6+/-1.1 vs. 9.8+/-1.3, P=0.001; 1.0+/-0.7 vs. 13.4+/-1.1, P<0.001). Migrated endothelial cells was significantly fewer in 20% and 40% medicated serum groups containing Scutellaria barbatae D. Don than in 20% and 40% drug-free serum groups (19.75+/-2.63 vs. 24.25+/-2.06, P=0.038; 14.00+/-2.58 vs. 26.5+/-4.65, P=0.006). When treated for 24 h and 48 h, the expression of VEGF in HeLa cells was significantly lower in 40% medicated serum group containing Scutellaria barbatae D. Don than in 40% drug-free serum group (138.67+/-9.50 vs. 195.82+/-2.43, P=0.006; 93.84+/-41.11 vs. 193.68+/-18.37, P=0.036). CONCLUSION: Scutellaria barbatae D. Don could efficiently inhibit angiogenesis in tumor tissue which might relate with inhibition of endothelial cell migration and down-regulation of VEGF in tumor cells.

AIM: To explore the abnormal function of platelets and the role of angelica sinensis injection (ASI) in patients with ulcerative colitis (UC). METHODS: In 39 patients with active UC, 25 patients with remissive UC and 30 healthy people, alpha-granule membrane protein (GMP-140) and thromboxane B(2) (TXB(2)) were detected by means of ELISA, 6-keto-PGF(1a) was detected by radioimmunoassay, platelet count (PC) and 1 min platelet aggregation rate (1 min PAR) were detected by blood automatic tester and platelet aggregation tester respectively, and von Willebrand factor related antigen (vWF:Ag) was detected by the means of monoclonal -ELISA. The 64 patients with UC were divided into two therapy groups. After routine treatment and angelica sinensis injection (ASI) + routine treatment respectively for 3 weeks, all these parameters were also detected. RESULTS: The PC, 1 min PAR and levels of GMP-140, TXB(2), and vWF:Ag in active UC were significantly higher than those in remissive UC and normal controls (P<0.05-0.01).Meanwhile, 1 min PAR and levels of GMP-140, TXB(2), and vWF:Ag in remissive UC were still significantly higher than those in normal controls (P<0.05). Furthermore, 6-keto-PGF(1a) level in active and remissive UC was remarkably lower than that in normal control (P<0.05-0.01). These parameters except 6-keto-PGF(1a) were significantly improved after the treatment in ASI therapy group (P<0.05-0.01), whereas they all were little changed in routine therapy group (P>0.05). CONCLUSION: Platelets can be significantly activated in UC, which might be related with vascular endothelium injury and imbalance between TXB(2) and 6-keto-PGF(1a) in blood. ASI can significantly inhibit platelet activation, relieve vascular endothelial cell injury, and improve microcirculation in UC.
